Swap all the wiring and diagnostic switches over. Then you are good to go, plug and play.

LTG : )

can you just swap out wiring harness?

I've done this. I did this with my Whirlwind and Black Knight 2000 because I wanted to have the upper DBV to install a Pinnovators headphone jack (at a show so that players could actually hear the game's audio). I had to wire a custom bridge (wiring harness) between the two connector configurations.

The one caveat is that the button configuration between the doors is not the same. The System 11 door is a 3 button with two side momentary switches. The WPC is a 4 button with all momentary switches. They are also electrically different (but not impossible to bridge).

The work around for this I had was to hold the momentary switch in for the switching functionality. It's a little bit of a pain and probably completely unintuitive for those that don't know what's going on. I need to further investigate the possibility of moving the 3 button assembly from the System 11 door to the WPC door.

Anyone ever make a bridge harness wiring diagram available or list how to match up the pins?

I have a High Speed that m6 coin door is garbage and there are no system 11 coin doors available anywhere WPC doors are everywhere.

As said a couple times above, Swap out the wire harness for the coin door.

If you're attending the Northwest Pinball and Arcade Show come find me. You are welcome to see what I've done to my Whirlwind and Black Knight 2000. I think I also did it to my Laser War.

The fundamental problem you need to overcome is that WPC switches are dedicated grounded switches whereas the System 11 switches are either a combination of dedicated grounded momentary and latching or are on the switch matrix and therefore require a diode. For System 11 only the diagnostic switches are the dedicated grounded momentary and latching. Everything else (including the high score reset switch located near the diagnostic switches) are on the switch matrix.

I would consider what I've wired as v1.0. I'd like to either swap the 3 switches or find a latching switch to replace one of the WPC momentary switches. I wired up the harness because it's reversible. I can remove the harness and use the coin door in a WPC machine with no further modification.

I will PM you - I am planning on having at least one of my games there - maybe my beat up High Speed with the hacked coin door. If that is not ready I will bring something - planning on being there for a good period of time. Definitely would like to see what you did - I had to use another coin door from Grand Lizard to just set the game to free play - maybe I just have a bad switch and need to replace it because once I swapped the door briefly I was able to change settings.
